SHELDON, Iowa -- Four fire departments battled a major blaze early Tuesday morning at a northwest Iowa printing company.

The Sheldon Fire Department was dispatched at 1:20 a.m. Tuesday to White Wolf Web, located at 300 Second Avenue.

The fire departments from Ashton, Boyden and Sanborn were also dispatched to help fight the blaze.

White Wolf Web is part of the Iowa Information Group, which publishes two newspapers, including the Northwest Iowa Review and other area publications.

"It burned in the early morning hours," said Myrna Wagner, one of the owners of the group. "I don't know anything in terms of cause or origination or anything like that."

Wagner complimented the volunteer firefighters who responded in the middle of the night to the blaze.

"We have an amazing group of firefighters that were out there for hours --volunteer fire fighters that dropped everything and came to help," she said.

The Iowa State Fire Marshal was on the scene Tuesday afternoon in an effort to find out more information.

The building was home to pre- and post-press equipment.

"We are so grateful there was no one in the building at the time, and no one was injured," Wagner said. "One of our drivers came to pick up papers and saw smoke."

The building may not be a total loss, but "at least a portion of it is. It's a building that has been added on a number of different times," Wagner said.

The company's printing will be handled at other facilities for the time being.

"We are working with different printers to make the process as seamless as possible for our customers," Wagner said.

Wagner and her husband, Jeff, received the call in the early morning hours and were on the scene by 2 a.m.

"There a time where you don't know, there is an unknown time from the time you get the phone call to actually seeing it yourself. I was shocked," she said. "My two big things are I'm so grateful there was no one in the building and thankful for the firefighters who tried to save our business. That's the words one of them used. These are people you know. You live in a small town, you know these people. He said to me, 'We weren't able to save much for you.' I thought wow, what a great view of what he was doing."
